But there is a huge different in scale: in the cement kiln temperatures reach over 1500°C, whereas clay is calcined at 650-850°C. Calcined clay production thus consumes less than half of the specific thermal energy of clinker production. Even more importantly – and unlike limestone – calcining clay does not release CO2.

The agriculture sector in Oman, like in many other countries in the Gulf region, is based on irrigation. While blessed with rich groundwater resources in many parts of the country, Oman s agriculture is plagued with salinity, and most recently sea water intrusion due to excessive pumping in coastal regions, where the main agricultural land is located.
The key for successful moisture determination, efficient productivity, and superior product quality is fast test determination without lengthy pauses in production processes. Successful moisture analysis means testing at the point of processing, and making adjustments before product integrity is effected.

Absolute humidity is a measurement of the literal amount of mass that the moisture has in the air around you. To find the absolute humidity of an area, you divide the mass of water in the air by the mass of air in the area. This metric is typically expressed as grams of moisture per cubic meter of air (g/m³).

Limestone isn't all that different from poured concrete- when you insulate it the temperature drops, and the moisture migration slows. When you also factor in the vapor retardency of the it changes the direction of the major flow from inward (toward the basement) to upward, drying toward the above-grade exterior.
